Loop and saddle connection system and method for mechanically stablized earth wall
A loop and saddle assembly includes a loop member and a saddle member. The loop member may include multiple layers (preferably 4 layers) of a geosynthetic material. The saddle member may have a curved seating surface adapted for cooperative engagement with the inner surface of the loop member. The saddle member may include a first generally planar truncated end at a first end of the curved seating surface and a second generally planar truncated end at a second end of the curved seating surface. The saddle member may include a lower surface with a concave profile extending from the first truncated end to the second truncated end. The loop member may be cast into a precast concrete panel with a portion of the loop member extending out of the precast concrete panel. The saddle member may be disposed in cooperate engagement with the loop member inside the loop member.
1. A loop and saddle assembly for engagement with a precast concrete panel comprising:
a loop member comprising multiple layers of a geosynthetic material, the loop member including an inner surface having a loop radius; and
a saddle member having a curved seating surface adapted for cooperative engagement with the inner surface of the loop member, the saddle member further including a first generally planar truncated end at a first end of the curved seating surface and a second generally planar truncated end at a second end of the curved seating surface, the first and second generally planar truncated ends being disposed opposite one another, and the saddle member further including a lower surface extending from the first generally planar truncated end to the second generally planar truncated end.

3. The loop and saddle assembly of claim 1 , wherein the curved seating surface of the saddle member has a saddle radius substantially equal to the loop radius.
4. The loop and saddle assembly of claim 1 , wherein the curved seating surface of the saddle member is recessed and includes a first side wall and a second side wall, the curved seating surface being defined between the first and second side walls.
5. The loop and saddle assembly of claim 4 , wherein the first side wall and second side wall are spaced apart by a distance slightly greater than a width of the loop member.
6. The loop and saddle assembly of claim 4 , wherein the loop member and saddle member are sized such that the loop member snugly fits within the recess between the first and second side walls.
7. A loop and saddle assembly for engagement with a precast concrete panel comprising:
a loop member comprising multiple layers of a geosynthetic material, the loop member including an inner surface having a loop radius; and

the saddle member further including a first generally planar truncated end at a first end of the curved seating surface and a second generally planar truncated end at a second end of the curved seating surface, the first and second generally planar truncated ends being disposed opposite one another, the saddle member further including a lower surface extending from the first generally planar truncated end to the second generally planar truncated end, the lower surface having a concave profile.
